This invention relates to'improvements in stamping machines of thetype shown in Pat ent No. 1,519,006 of Oscar M. Pannier. Machines of the character shown in said December 9, 19245, to

Letters Patentembody a plurality of master wheels operable by means of levers or handles to rotate pairs of'type wheels or gears, said type wheels heing mounted on relatively movable shafts and having embossing char acters on theteeth or projections thereof.

Spring and ratchet r'n-ezin-s are employed between the type wheels and their shafts for the purpose ofalining the ty 'oe-bearing pro jections on'said wheels prior to embossing.

Such construction is expensive and offers con-* siderable resistance to the operation. of the machine, and in addition, the ratchetmeans is not positive in its operatiompermitting the embossing mechanism to actuate the type Wheels when their type-bearing projections are out of alinement.

Our invention is principally directed to a machine of this character'heving freely rotata-ble' master and type Wheels or gears, and means operable to positively aline the characters on said type" wheels prior to their actuation in the embossing operation, where by is inipossible to injnrethe article being stamped through misaiineinent of said type; In the drawings which illustrate a preferred embodiment of our invention Fig.1 is a front elevationalview of the machine, partly in section; j I V ig. 2 is'a. vertical section taken on the line II'-II of Fig. 1; Fig. Sis an enlarged view oi the machine in front; elevation with the front portion'of the body removed to show the mechanism;

The upper end upper surface 24 of the cap 20, said abut-V 'ment and surface being normally spaced of the member 18 is loosely received in a cylindrical caporxclosure member 20 having a slidable connection with the member 14 by means of a stud 21- passed through an enl-arged.'- opening 22 in thesaid closure member 20.: I i v The upper end of said studis fixedly secured in the member 14 and has an arcuate abutment 23-thereon for engagement by the apart, as shown inFigs'. 1 and 2.

Said'block 27 and plate3 are formed with alinod'oponings 2 8 and 29'to permit a stem 30 of the dog 25 to pass therethrough and reciprocate therein. V,

Similarly, the dog 26. is horizontally slid,- able in a grooved block or member 31, but said block is secured to and movable ver tically with themember.14, said block31 being vertically movable ina recess 32 in "the inner face of the rear plate 3. A; rearwardly extending stem 33 on thedogl26 is movable both vertically and horizontally in alined openings '34 and 35 in the block 31 and plate 3 respectively. p

The stems 30 and 33 of dogs 25 and 26 extend rearwardly beyond the plate 3 and are received between spring-pressed members 36 and cam followers 37 horizontally slidable in grooved retaining blocks .38,secured' to the The action of. springs 36a on members 36 serves to normalrear face of the ,plate 3.

A vertically disposed cam. 39 is passed through the blocks 38 in therear of the plate 3 in contact with an end of each of the followers 37, and is provided with si1nilar'slop-. ing' camsurfaces 40 designed to simultaneouslymove the dogs25 and 2 6. with respect 'to their type wheels, upon verticalmovement of said cam.

A lever 41 is pivoted to the rearface of the plate 3 at 42, having one end 43 thereof connected to the cam 39. and the other end pivoted to a'vertical pusher rod 44, secured to and movable with the cap member 20 on the hollow member 18.

The front and rear plates 2 and 3 are provided with corresponding openings 45 therethrough for receiving'the material to be embossed, and to afford visibility of adjacent portions ofthe type wheels 10 and 11 to the operator. One of said'wheels may be providedon the front peripheral portion thereof atthe teeth, with suitable 'indicia as in Fi 3, corresponding to the. type on said 'teeth. An indicator 46 is provided on the plate member 2, co-op'erating with the said indicia to indicate the character of theteeth b and 0 in-embossing relationshipi A suitable table, diagrammaticallyshown at 47 ,"may be employed for positioning and alining the material or blank 48 to be embossed between the type wheels 10 and 11, as will be readily understood. With the blank 48 positioned to bring'the area tobe embossed directly between the teeth band c'of the said type wheels, the operation of our invention is 'as follows. 7 Theoperator rotates the master "wheel 5 onits ball bearings 6 in either direction by grasping the pro ecting outer rim thereof, rotating the type wheels 10 and 11. until the desired character-bearingteeth b1 and care brought approximately into embossing position or vertical alinement, as shownby the indicator '46 and the indicia ,on one of said wheels. I

Rotation of the'foot pedal 16ab0ut its shaft 17 will raise the member 18 and its cap member 20 vertically on the stud 21, during I which movement the pusher rod- 44 is elevated, causing the lever 41 to rotate about its pivot42 and lower the cam 39 as in Fig. 3,

whereby the cam surfaces 40 thereof urge the followers 37 inwardly.

The said followers act upon the stems 30 and 33 of the dogs 25 and 26 to simultaneously move said dogs toward their respective type wheels 10 and 11. Continuedrotation of the pedal 16 until the top face 24 of ,the member 20 strikes the abutment 23] of the stud 21,

'wheel5 will be corrected by the entrance of y the projections c of the dogs 25and 26into' the teeth of, their respective-gears, prior to embossing. I

However, if the misalinement' is too great, the projections e on said dogswill strike the peripheries of their type wheels, thereby preventing the full travelof the pedal, and hence preventing surface 24 and abutment 23 from coming into operative engagement. c

I Thus it is seen that the dogs 25 and 26 and their associated mechanisms connected with the foot pedal 16 operate to either positive} l3] aline the character-bearing projections on their type wheels and 11 prior to the final or to prevent that in alinement by means of the dogs. Openings and clearances are provided forthe member 14 and the mounting for the dog 26 as stated,

7 scribed may take place,

whereby the vertical movement just de T Upon releasing or returning the pedalll6 to the normal position of Figs. 1 and 2, the

wheel ll and members 14, 20, a'nd lS are lowered out of embossing position, the cam 39 is elevated permitting the'followers '37 to be received in the sloping surfaces 40, and the dogs 25 and26 are moved out of engagement with their type wheels by the action of i the members 36 and their springs 360a.

The mounting of the master wheel 5 afiords an easy adjustment ofthe type WheelsIO and 11, as said wheel 5 is freely rotatable by the operator. With very little practice, one may become highly efiicient' in the adjustment of the type wheels, with "a minimum of effort and maximum speed.
